I tried to create a detailed response to this but in the end I gave up (also I have other things to tend to).

Please. It is not okay to keep supporting an idea until the minute the counter to that idea becomes available, when you'll be eager to benefit from the "counter" solution.

It was not okay for Ayn Rand to be a libertarian all her life, only to start collecting welfare checks at the end of her life when she went broke.

I'm not even getting into the practical aspects of how badly the pro-aging trance is affecting the funding problem.

Until the possibility is established, many people are going to make fun of, and sideline those working on a solution.

However, I think this thought experiment can bring them to understand that their own beliefs are temporary. If there was a popular movie that followed the plot of how the cure of aging was slowly accepted in society, for example.

Just a short story might be a start.

I think the problem is not that people "support" the idea, but that they are not properly aware of the alternative.

People have a fairly strict limit on the kinds of counterfactuals they can conceive, and thus use as "measuring sticks" for evaluating the actual facts. Even the very imaginative still require a leg up in terms of being told, sometimes, being supplied with information, that what their mind had registered as constant was actually quite variable.

Ayn Rand didn't change her views. Period. She was just blatantly self-serving.

Most people do not support some Moral Ideal of Death. They just consider the actual dying bit inevitable. This is why they will change their minds once you show, in the real world, that it's changeable.

I personally fear the aftermath, because we're venturing into unknown territory.

You're assuming that the treatment will be within reach for everybody. What if only rich people will be able to afford it?

If the treatment is a product of the current pharmaceutical industry, I think one might have to worry about that - especially in the beginning.

It might be seen as even less important than distributing food to the starving, and medicine to the sick, of which there is still not enough going on.

But there is at least one other pathway. As an AGI researcher, I believe that artificial intelligence will solve the problem for us, and, all other things being equal, the cure will be made available everywhere, at the same time.

My own research makes me believe that we are not very far from that outcome.

AGI-15 local chair here. Please, would you send me an e-mail (see profile)?

Well, if you're so close to so many major breakthroughs, mind showing a grad-student some publications? I'm always interested to see what sorts of learning and modeling go under the label "AGI".
